3 Claims.

This invention relates to vehicle window regulators, but more particularly to a power operated regulator for actuating a Ventilating vane on an automobile body of the type adapted either to scoop air inside the vehicle when in one position, or to exhaust fuel gases, smoke and the like from the inside of the vehicle when in another position.

An object is to produce a new and improved regulator mechanism of the above type which is adapted to rock the vehicle Ventilating vane to a selected position, the same being readily installed in the vehicle body and being controlled from a remote station.

Another object is to produce a regulator mechanism of the above character which is in the form of a unitary assembly and which can be readily and conveniently mounted in position of use and which is operable automatically to rock the Ventilating vane to the desired position of adjustment.

Other objects and advantages of the invention will hereinafter appear, and for purposes of illustration lbut not of limitation, an embodiment of the invention is shown in the accompanying drawings, in which Figure 1 is a fragmentary elevation of a side portion of an automobile body showing a ventilating vane;

Figure 2 is an enlarged transverse sectional View on the line 2-2 of Figure 1;

Figure 3 is an enlarged side elevation of the regulator mechanism installed in position of use, the adjacent vehicle body portion being shown in section and broken away;

Figure 4 is an end elevation of the regulator mechanism; and

Figure 5 is a sectional view substantially on the line 5-5 of Figure 3.

The illustrated embodiment of the invention comprises a side wall panel I of an automobile body or door, provided with a triangularly shaped window opening Il which is adapted to be covered by a window glass I2, two sides of which are enclosed by a channel frame I3. The rearward edge of the window glass I2 is adapted to abut against a window'glass I4 which is suitably mounted in the panel I0. The frame I3 is mounted for rocking movements about an up and down axis, there being a pintle I projecting upwardly from an upper portion of the frame into a suitable bracket I6 and depending from the lower portion of the frame I3 is a shaft I1 which projects through an opening I8 in a vehicle part I9. The shaft I1 is rectangular in cross section and fits into a socket member 20 and is secured in place by a screw 2I. The socket member 2l) is rigid with a shaft 22 which is journalled ina frame part 23. I

On the lower end portion of the shaft 22 is an arcuate flange 24 which is adapted to rotate in a groove 25 in the regulator frame and directly beneath the flange 24 and on the opposite side of the shaft 22 are gear teeth 25 meshing with teeth 21 on a sector 28. l Directly above the flange 24 is an-undulated spring washer 24a which exerts a spring pressure against the flange and serves asa-brake to hold the shaft I1 in the position of adjustment, thereby eliminating unwarranted rocking movement of the shaft. The sector 28 is mounted on a shaft 29, the upper and lower ends of which are cylindrical to rotate in bearing bosses 30 and 3| respectively. The'shaft'29 intermediate the end portions is squared in cross section and the gear sector 28 is provided with a square hole to fit the squared portion of the shaft. Manifestly, by rotating the shaft in one direction, the vane or window glass l2 is rocked to and from closed position. Figure 2 indicates the arc of movement of the window glass from its fully open position to its closed position.

The frame which supports the regulator mechanism may be formed from a die casting and has a body 32, an upper ange 33, a lower ange 34 and end flanges 35 and 3G. The bearing portion 23 and bearing boss 30 are integral with the ange 33 projecting upwardly therefrom. Reenforcing webs 31 and 38 reenforce the bearing portion 23 and screws 39 extend through the vehicle part I9 to assist in mounting the frame in position. Likewise, screws 4U connect the body 32 of the frame' to a suitable supporting panel,

is one end of a helically coiled spring 46. The

opposite end of the coil spring 46 hooks over the ouer side of a compensating arm 41, the opposite end of which is pivoted on a stud 48 mounted within an arcuate corner extension 49 of thel frame." The opposite' or free 'end of the compen-J sating arm 41 projects into a slot 50 in the flange 33 of the frame to afford limited rocking movements of the arm. As will hereinafter more fully appear, the coil spring, through the connections described, actuates the Ventilating vane or window glass I 2 to open position.

For actuating the Ventilating vane in the opposite direction, or toward its closed position, a piston and cylinder assembly I has one end connected by a suitable clip 52 to the compensating arm 41 on the end portion adjacent the pivot stud 48, the piston rod 53 of the assembly being connected by a suitable clip 54 to the outer end portion of the lever arm 44 of the actuating member 4|.

Detail illustration and description of the piston and cylinder assembly 5I are not given because the same forms no part of the present invention. Suffice it to say that liquid under pressure is forced into the cylinder through a tube 55 to force the piston rod outwardly of the cylinder. Within the cylinder is disposed a solenoid control valve which is adapted to be energized through a lead 56 and upon being energized, the valve is unseated to permit the introduction of pressure fluid. When the solenoid is deenergized, the valve is seated to trap the liquid within the cylinder, thereby to hold the piston in its position of adjustment. Manifestly, the outward movement of the piston rod 53 rocks the actuating member 4I and places the coil spring 46 under tension. When it is desired to open the window glass 2, the solenoid within the cylinder 5| is energized and through the action of the spring 46, the piston rod and its piston is moved inwardly of the cylinder, forcing the liquid therefrom through the tube 55. Reference is hereby made to my Patent No. 2,400,572, dated May 21, 1946, wherein a complete description and illustration of this mechanism is set forth.

From the above description, it will be manifest that I have produced an exceedingly simple, compact, unitary assembly which can be delivered to the automobile or body manufacturer as a unit for installation either in the door of the vehicle or in the vehicle body, according to the position of the triangular Ventilating vane. The fra-me can conveniently be produced from a die casting or from a stamping, the assembly being exceedingly simple. Provision of a compact unitary assembly of this character obviates difficulties heretofore experienced in the mounting of the various parts within a vehicle body` It is further to be understood that the structure can be controlled from a single switch which controls the electrical current to the solenoid control valve above mentioned, and which is part of the piston and cylinder assembly 5l. It will further be. rec.q ognized that the actuating unit, together with the toothed members, affords substantial power for eecting the desired window movement.

It is to be understood that numerous changes in details of construction, arrangement and operation may be eiected without departing from the spirit of the invention especially as defined in the appended claims.
